IMPROVED DEVICE FOR 'RA I' SING WATER BY STEAM Specification formingpart of Letters Patent N 36,661, dated October 1-1, 1962.

Zb aZZ whom it may concern.-

Be it known that I, W'. \V. MARSH, of St.

Louis, in the county of St. Louis and State of I Missouri, have inventeda new and Improved SteamSiphon; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing bad to the accompanying drawing, forming apart ofthisspecification.

The drawing represents a vertical central section of this apparatus.

To enablethose skilled in the art to make and use my invention, I willproceed to describe its construction and operation with reference to thedrawing.

A represents the steam-pipe through which steam is admitted from a steamboiler by opening a suitable stop valve or cock. This steampipe may bemade of india-rnbber or other flexible material, and it ought to beprovided with a suitable contrivance enabling the operator to'eonnect iteasily to any steam-boiler.

' The mouth of the steam-pipe is firmly eon nectedto aT-shapedconnection, B, and it extends through the head of said T-shapedconnection into the in'ner'en l of the deliverypipe 0, which insertedinto the T-shaped connection 13 in suclna manner thatit runs for ashortdistance in the same direction as the mouth-piece ol' thesteam-pipe. The inside.

diameter of the deliverypipe is somewhat larger than the outsidediameter of the mouthpiece of'steam-pipe in order that an annular space,a, ma be left around the latter.

1) is the suction-pipe,which is inserted into the Tshaped connection atright angles to the two other pipes, and'whiclr connects directly withthe annular space a, surrounding .into tludelivery-pipe directlyopposite the mouth of the stezun-pipe, and pointing toward the latter,for the purpose of spreading the steam as it issues'i'rom thesteam-pipe, and to facilitate the expulsion of t he air and the actionof thesteam on the water after the latter begins to flow. h

The operation 1s as follows: The length of the suction-pipe having beenadjusted to the height to which it is desired to raise the wa ter, itslower end is immersed into the well, reservoir, or vessel containing thewater, and the steam-pipe isconnected to a steam-boiler. The steam valvebeing opened the steam rushes through the steam-pipe and through thedelivery-pipe, thereby expelling the air .from the latter, and causing adraft over the upper end of the suction-pipe, whereby the air containedinthe same is impelled to rush out through the annular space a, and tobe carried ofi with the steam. By these means the 'air int-hesuction-pipe is rarefied,and the atmospheric pressure causes the waterto rise in said pipe and to rush out through the delivery-pipe.- If oncestarted, the water is carried out through the latter pipe with aveloe-ity corresponding to the pressure of the steam issuing from thesteam-pipe, and a very large quantity of water can thus be raised in acomparatively short time.

This apparatus is particularly applicable to ships pumps onsteam-vessels, and one of its chief advantages consists in the totalabsenee of all valves, so that all impurities contained in or floatingon-the water pass through without obstruction, and that such impuritiesare not liable to interrupt the correct action of the apparatus.

Said apparatus is very simple in its construet-ion, it can easily bearranged in working position, it takes up very little room, and

it is not liable to get out of order.

it renu'tins to remark that compressed air may be used in place of steamto effect the same pu'rpose,such air being admitted through the pipe inthe same manner as the steam, as

above described.

1 do not broadly claim the useof steam 'for the production ot avac uumand the driving of water; but

\Vhat 1 claim as new, and desire to secure by Letters Patent, is

The combination. of the cone b with the pipes O A l), in the manner andforthe purpose herein shown and described.
